I don't know, I don't vaccinate, I cull any that show symptoms and allow a natural immunity to build up. I had a few birds a few years ago but haven't had any since. I do read now where turkeys carry a less dangerous strain that can give chickens immunity, so perhaps my turkeys have made it so my birds don't come down with it anymore, and I only buy chicks from a single source. Hopefully someone who vaccinates can help out.
Edited to add when I did have some with Mareks it was random and only a few young birds, it didn't wipe the whole batch out and was limited to a couple birds, one batch was from a swap meet, then the next year from the farm store, than nothing ever again.
That is how I feel, and what I am thinking. Just panicking over my daughters birds, These birds I have lost are all from the same breeder. I am thinking of continually hatching out my brahmas and let them build immunity natural way. The strong will survive and the sick I will cull. If I breed a lot, then I will lose some but have a stronger flock down the road. I was also considering getting turkeys because I also heard they help build immunity naturally. My husband said he was alright with the idea. Now to find turkey eggs.
